y Appiication filed september 16,1925. serial No.1 56,679.. w A u TTh@Present lvention relates to a washing machine. f

" .A desirable method .of washing clothes,v

and one which produces a minimum of wear *on clothes during awashingoperation,I is

tofforce soapy waterfthrongh the fabric of Vin the machine,'saidwaternbeingV carried i back by gravity and driven through theV fabric ofclothes contained in the cylinder to clean them. i .7.

Another object of the invention-is to Iforni ai washing machine cylinderywith channels Vin the periphery thereof toV carry water which will beforciblydriven through the clothes to clean them.

' Inl'order .to attain these. objects,r thereis provided, in accordancewith vone Vfeature of the invention, a cylinder having aplurality of.corrugations in .the drum' thereof, Vsaid corrugations being continuousthroughout the circumference ofthe drum, the inward foldV of eachrcorrugationbeingprovided withV apertures therein for the .admission.therethrough ofV water to the interior'gof the drum,rand the outer foldof eachcorrugation being continuous `and substantially water" tightthroughout the entire circumferenc'eof the cylinder.

These and brought out in the following description and the accompanyingdrawings, wherein: v Figure 1, is aview in side elevationof a washingmachine ofthe rotating Cylinder*V type,w1th a cylinderlmadenn accordancewith the present invention. installed therein,

a portion of the water `compartment ofthe in l transverse section Ythrough the cylinderfshowing the construction thereof and the.positioningofbattens or .lifts therein, the-action of water thereinduring a washing operation beingindicated by dotted lines and Y f Figure3, is an enlarged vsectional view-ofl i a Yportion of` a removable covermember posA otherv features ofthe invention,` notspecifically.mentioned,willbe more fully j l s itioned over the openingin the cylinder for the adinissionof clothes. Referring to the drawingsin detail, ya

A washing machine Afcomprises a base Iportion 'y 1' having avmotor 2mounted therein in the motor lane vconnected through shafts and gearsVinfafwell known manner" toqajdrive Vmechanism Since the drivel mechanismof the machine illustrated'lis of a common type7 andjsince various typesof drive Amechanisms may be'eniployed"without departing.

from the invention, it is unnecessary to de# scribe thedrive"mechanismpin detail.-A A

clothes wringer .4Y ispivotally-mounted on top of awringer 'drivemechanism 5.

A water lcompartmei'it 6 is constructed of sheet` metal and is provided`with .acock l v7 y means of which the water ment may` be'drainedf; f ,f

l.AcylinderB 's provided vwith'discoid ends 8k which may be of f sheet'metal,"tlie end .shown in Figure 1 lbeing. `provided with a stub; shaft9 fitted toV the .center thereof. The" shaft 9.k is supported forpivotal. move? ment ina bearing 10, the other end. of theV cylinderbeing .centrally pivotally A supported with respect to lthe operative'drive j mecha-` nism tobe oscillated thereby-j A corrugated casing 'orlrum 11 is integrally secured to the discoid: end members 8 'as by.'flanging at 12. Thedrum is provided `with a plurality. ofcircumferential corrugations. 13 concentric with the discoid vends 8,the inner folds of the corrugations being preferably flattened as at 14and pro-V vided with aplurality of vholes 15'v on the inner folds yofsaid corrugations.

The corf leo Y rugations, forthe purpose of the invention,

are preferably,V fairly large,'about six being employed ina vcylinderapproximately eight@4 Y een incheslong. A pluralityv ofl battens orlifts 16 are'secured to the interior face of;v

the cylinderto entend longitudinally thereof, fiveof such lifts beingillustrated in the i i present'-instance. l v Y A cover" 17'is provided,having corruga-V tions therein to c orrespondto the corruga- -tions inthe. cylinder, the cover extending` the entire length of thecylinder.Afxed to each edge ofv'the cover is'a reinforcing 'and cover retainingmember 18 whichfisA inte`- 'grally secured tothe cover memberas by spot1 welding to extend beyond the end thereof and supportinglyr rest onvtheedgeeof'the cylinder adjacent the cover opening. The cover tits into theCover'opening to lie flush therewith onv its inner side so as to provideuninterrupted channels throughout the entire circumference of thecylinder in each of the outward folds ofthe oorrugations 13 Theo-ilinder is preferubly rotated a precleterni'ined numberotrevolutii'ins in one direction and is then automatically reversed androtated a predetermined number ot revolutions in the opposite vdirectionin accordance with' ai Well known principle of operation oi cylindertype Washing machines.

Duringa Washing operation' the Water in the channels formedby the outertelde ot' the corrugations 13 is forced, by the action of the lifts 16and the friction between the Water and said channels, to flow in thedirection ot' rotation ofthe cylinder, and is carried by the channels'above the normal level 03: the Water in the container. t then' Vfallsback by gravityVas shown in dotted Well as vthe normal currentspreviously Vmentloned, act to torce the Water through the clothes, whichare also kept 1n' agitated vcondition by the rotation of the cylinder.

from the container by means of the drain cock 7. In' orderv tocompletely drain the cylinder it may be manually -rotated to bringthecover opening on the` lower Side of the cylinder to permit the Water toflow out ot the channels formed-by the outer folds ot the corrugations13;

What I claim is: Y

l, rr Washing machine cylinder hai/ing discoid end members centrallySupported for oscillation ina Water container, a perforated Wallconnected to the peripheriesot said end members, seidY Wall having:r aplurality Aof unpertorated Continuous annular channels therein., andbattons connected to the interior oi the Wall tobridge said channels. Y

2. A Washing machine cylinder having a plurality ol corrugations in theperiphery thereof, said corrugation's Ybeing continuous throughout theperiphery ot the cylinder to form channels encircling` said cylinder,said corrugations being provided With apertures in the innerioldsthereot only, and a plurality ot battens mounted transversely ot' thecorrugations tor bridge the' channels formed thereby; Y Y Y In testimonywhereof I aitix my signature.
